Sewing tape

ABSTRACT

The sewing tape consists of a strip of thin flexible material having adhesive material on one surface thereof and a plurality of longitudinally extending lines of perforations. The lines are spaced 1/16th&#34; apart and the perforations in each of the lines are spaced 1/16&#34; apart and in registration with the perforations in the other lines so that the perforations form both longitudinal and transverse lines spaced 1/16th&#34; apart on the tape. Certain of the longitudinal lines of perforations are marked with longitudinal guide lines spaced given distances greater than 1/16th&#34; apart, and certain of the transverse lines of perforations are marked with transverse guide lines spaced given distances greater than 1/16th&#34; apart and extending in alternate fashion from opposite edges of the tape for distances less than the width of the tape. Each repeat length of the tape is composed of two sections having body portions similarly marked as aforesaid, and having end portions provided with guide lines forming continuations of said longitudinal guide lines, but of varying lengths and terminating in transverse guide lines extending to a longitudinal edge of the tape; such transverse lines in one end portion extending to one longitudinal tape edge and the transverse lines in the other end portions extending to the other longitudinal tape edge.

SEWING TAPE I ,Filed June 19, 1972 U ited States Patent Int. Cl. B32b 3/10 US. Cl. 161-109 3 Claims ABSTRACT OF THE DISCLOSURE The sewing tape consists of a strip of thin flexible material having adhesive material on one surface thereof and a plurality of longitudinally extending lines of perforations.- The lines are spaced apart and the perforations in each of the lines are spaced A apart and in registration with the perforations in the otherlines so that the perforations form both longitudinal and transverse lines spaced apart on the tape. Certain of the longitudinal lines 'of perforations are marked with longitudinal guide lines spaced given distances greater than apart, and certain of the transverse lines of perforations are marked with transverse guide lines spaced given'distances greater than A apart and extending in alternate. fashion from opposite edges of the tape for distances less than the width of'the tape.'Each repeatlength of the tapexis composed of two sections having body portions similarly marked as aforesaid, and having end portions provided with guide lines forming continuations of said longitudinal guide lines, but of varying lengths and terminating in transverse guide lines extending to a longitudinal edge of the tape; such transverse lines in one end portion extending to one longitudinal tape edge and the transverse lines in the other end portion extending-to the other longitudinal tape edge.

This invention relates to an adhesive tape for use as a guide in the making of fabric articles, such as garments.

The primary object of the invention is to provide an improved pressure sensitive sewing tape that is readily adaptable to a wider variety of uses than known tapes of this type and which enables the user to perform more accurate sewing operations than is possible with prior sewing tapes.

Other objects of the invention as well as the advantages and features of novelty thereof will become apparent from a perusal of the following description, when read in connection with the accompanying drawings which shows in plan view, a portion of a preferred form of tape embodying the invention.

In the drawing the numeral 1 indicates a partial repeat length of a continuous length of tape embodying the invention. The tape is constructed of a suitable thin material, such as paper or plastic, that is preferably colored yellow to make is readily discernible on most colored fabrics and to provide a distinctive background for the guide lines provided on the facing surface 2 thereof. The other or back surface of the tape is provided with a coating of adhesive material, such as a well known make of pressure sensitive adhesive material. As indicated in the drawing, each repeat length of the tape is composed of two sections 3 and 4 of equal length, about 7".

The flexible body material and adhesive coating of the tape is provided throughout the entire length of the tape with a plurality of longitudinally extending lines 5 of small perforations 6. The longitudinal lines 5 of perforations are spaced A apart and the perforations 6 in each longitudinal line thereof are spaced apart and are in registration with the perforations in the other lines. As a consequence the perforations form both longitudinal lines 5 and transverse lines 7 spaced A apart throughout the entire area of the tape. The strip is preferably 3,794,554- Patented Feb. 26, 1974 made /1" Wide'with the lines of performations spaced from each of the sides 8 and 9 of .the tape. Accordingly, there are provided on the tape eleven longitudinal lines 5 of perforations 6.

Each of the sections 3 and 4 in each repeat length 1 of the tape is marked throughout the major portion of its length, about 5 /2", with four imprinted longitudinal guide lines 12, 13, 14 and 15 and a plurality of alternately arranged imprinted transverse guide lines 16 and 17. The remaining minor portions of sections 3 and 4, approximately 1 /2" in length, are marked with imprinted extensions 12, 13,,14 and 15 of the guide lines 12, 13, 14 and ,15, respectively, and which are terminated by transverse imprinted guide lines extending to one of the longitudinal edges 8 and 9 of the tape. The ends of the minor section portions are defined by and separated from the major section portions throughout the length of the tape by transverse lines 18 and 19 which preferably extend across the entire width of the tape.

It will be noted in the drawing that the four longitudinal guide lines 12, 13,14 and 15 are spaced A3" apart and mark four of the longitudinal lines of perforations 5. One end guide line 12 is spaced A" from the tape edge 8 and the other end guide line 15 is space A" from the top edge 9. In the sections 3 of the repeat lengths on the tape, the extensions 12, 13', 14' and 15' of such guide lines have associated therewith the symbols A3, /2, and A, respectively, to designate their spacing from the tape edge 9 and the lengths of the terminal transverse lines connected thereto. On the other hand, in the sections '4 of the repeat lengths on the tape, the extensions 12', 13, 14 and 15' of such guide lines have associated therewtih the symbols A3, A, and /2, respectively, to designate their spacing from the tape edge 8 and the lengths of the terminal transverse lines connected thereto. The aforesaid symbols are placed within the angles formed by the said extensions with the terminal transverse lines joining them. It will be noted that in the repeat length sections 3, the extensions 15, 14', 13' and 12' are pro gressivelyof longer length toward the associated transverse line 19 and that the terminal transverse lines 20, 21, 22 and 23 which are respectively connected thereto and extend therefrom to the tape edge 9 are progressively longer toward their associated lines 19. On the other hand, in the repeat length sections 4, the extensions 12', 13', 14' and 15' are progressively of longer length toward the associated transverse line 19, and their terminal transverse lines 23, 22, 21 and 20', respectively, are progressively longer toward their associated lines 19 and extend to the tape edge 8. Associated with each of the transverse lines 19 is the symbol indicating the length of such line and the width of the tape. In the sections 3 such symbol is located in relation to the associated lines 19 adjacent to the tape edge 8, and in the sections 4 such symbol is located in relation to the associated lines 19 adjacent to the tape edge 9. Thus, the aforesaid symbols in the repeat length sections 3 form an inclined series extending from the end longitudinal guide line extension 15' to the tape edge 8, while in the repeat length sections 4 they form an inclined series extending from the end longitudinal guide line extension 12 to the tape edge 9.

With respect to the transverse guide lines 16 and 17, it will be noted that they are wholly contained in the major portions of the sections 3 and 4 and in each such section portion, extend in separate series longitudinally of such portion. The series of guide lines 16 start A" from a transverse line 19 and end A" from the associated transverse line 18. The lines 16 in the series are spaced /2" apart and mark transverse lines 7 of the perforations from the longitudinal line 14 to the edge 8 of the tape. The series of guide lines 17 start /2" from the same transverse line 19 and end /2 from the associated 3 v transverse line 18. In such series the guide lines 17 are spaced /2" apart and mark transverse lines 7 of the perforations from the longitudinal line 13 to the edges 9 of the tape. Thus, the guide lines 17 are spaced apart from and are alternately arranged with respect to the guide lines 16, with the inner Ma end portions of both guide lines in alignment between the longitudinal guide lines 13 and 14. A suitable symbol Z is provided to indicate the /2" spacings between said transverse guide lines 16 and 17 in each series thereof.

It will be understood from the foregoing, that in the use of the tape a suitable length of the same is cut off from the roll using the transverse printed lines 16 and 17, and the transverse lines 7 of perforations as guides. The tape is then pulled apart along a line of perforations using such line and the printed guide lines 12, 13, 14 and 15 to obtain an accurate width of tape for the purpose desired. If a width of tape greater than A is desired, two lengths of tape is utilized using the full width of one length and any desired part of the width of the second length. The tape is placed on the fabric with one edge thereof at the seam or cutting line and the opposite edge thereof is used as the stitching or cutting guide. Preferably, the applied line of stitches or the cutting operation is made exactly next to the edge of the tape, not through it.
